What are sound waves with frequencies below normal range?
Infrasounds (frequencies under 20 kHz)
Sound waves with frequencies below the normal human range of hearing are called?
Infrasound.
How many normal modes of oscillation or natural frequencies does a mass oscillating on a spring have?
Get a screen door spring. and then hang a mass on it. Carefully lift it and then let it drop, that gives it up and down motion. Stop the mass, twist it, and then let it go - torsional mode. Stop it and pull it to one side. Now you have a paraconic pendulum. If it's stopped, and you hold the spring where the mass is attached to the spring, turning the mass level (90 degrees from spring axis) counteracts gravity, and the mass will rotate about its center of gravity. Perhaps the spring alone can oscillate. Hold the mass where the spring is attached, and pluck it in the middle If you're not careful in your release, any or all of these can happen at the same time. Since any and all can happen at the same time, then if I counted right, that's 720 modes already.
What happens to pendulum clocks in summer?
Because the period is based on the length of the pendulum, an increase in temperature (such as that as occurs in summer) will make the material, normally metal, in the pendulum expand - which is why better clocks often had wooden pendulum rods. Since it is longer its period increases and makes the clock run slower than normal. Numerous inventions were developed to counteract this effect, most taking advantage of the properties of thermal expansion of various materials and how they are arranged in the pendulum.
How can the period of a pendulum be calculated?
Without going through all the derivations, unless some one wants me to (I could show you my physics notes), the equation for a period of a pendulum with small amplitude (meaning reasonable amplitudes, i.e. less than 45O from the normal) is : T = 2 * Pi * sqrt(L / g) where L is the length of the pendulum g is the acceleration due to gravity where ever the pendulum is (9.8 m/s2 on earth)
What is negative damping?
It is the opposite of normal damping (oscillation decreases), so in negative damping to get even bigger oscillation.
What are sound waves with frequencies below normal range?
Infrasounds (frequencies under 20 kHz)
What is the name of the weight on the end of pendulum?
The normal term is "bob."
What are sound waves with frequencies above the normal human range of hearing?
Sound waves with frequencies above the normal human range of hearing are called ultrasoundUltrasoundUltrasonic for frequencies higher than a human can hear, and infrasonic for those frequencies below the human threshold of hearing.
Sound waves with frequencies above the normal human range of hearing are called what?
Sound waves with frequencies above the normal human range of hearing are called ultrasoundUltrasoundUltrasonic for frequencies higher than a human can hear, and infrasonic for those frequencies below the human threshold of hearing.
What is inaudible sounds?
frequencies that are out of normal hearing range.
Why time period of pendulum depends on length not other factors?
It does depend on the force of gravity where the pendulum is located. There are other factors that it depends on but their contribution, in normal circumstances, is negligible enough to ignore.
How a Oscillator works without giving any input signal?
just like the simple oscillator that v c in our normal life which is a Pendulum. in pendulum there is the difference between the potential energy and then the theory of inertia is applied similarly it happens with the case in the electronics whr the +Vcc voltage is there and its difference with the ground helps in oscillation using the tank circuit. shri krishan sharma
Do ultrasonic waves have frequencies higher than normal human hearing?
That is the definition of ultrasonic!
Sound waves with frequencies below the normal human range of hearing are called?
Infrasound.
